Q2: Wire loops coaxial with a current carrying wire
The two circular wire loops represented above are coaxial. If the current I in loop A is increasing linearly with respect to time, which of the following is true of the induced current in loop B? Lenz's Law - seeing that the magnetic field induced by a current induced by a change in magnetic flux (Faraday's Law) counteracts the change in flux. If current in loop A is increasing, the magnetic flux pass loop B is increasing too. loop B will produce a current which counteracts the change of loop A.
